美国科研人员在亚利桑那州图森沙漠北部进行的雄心勃勃的“生物圈二号”试验,不久前以失败宣告结束。这项耗资近两亿美元、探索人类和动植物在人工建造的占地约14万平方英尺的巨大温室中生活可能性的试验,由于遇到种种困难而失败。在这个以玻璃、钢材为结构的巨大温室中,设有雨林、海洋、沙漠、草原、沼泽等部分,还有供8名试验人员居住的地方及其耕种的田地。按科研人员的本意,是让8名试验人员与3800种动植物在这个与世隔绝的环境中,通过水、空气和食物的循环利用来维持生命,而生物圈利用尖端科技控制温度和温度。然而,与科研人员意愿
The ambitious “Biosphere II” trial conducted by U.S. researchers in northern Tucson Desert, Arizona, ended shortly after the defeat. The experiment, which cost nearly two hundred million U.S. dollars to explore the possibility of human and animal life living in a man-made giant greenhouse of about 140,000 square feet, failed due to various difficulties. In this giant greenhouse of glass and steel, there are rainforests, oceans, deserts, grasslands and swamps, as well as a place for eight test workers and fields for cultivation. According to the researchers' intention, eight experimenters and 3800 species of animals and plants maintain their lives through the recycling of water, air and food in this isolated environment, while the biosphere uses state-of-the-art technology to control temperature and temperature. However, with the wishes of researchers
